Vedclass · Answer

(C) The Lassaigne test involves the fusion of an organic compound with sodium metal to convert elements like nitrogen,sulfur,and halogens into their water-soluble ionic salts ($NaCN$,$Na_2S$,$NaCl$,etc.).Sodium is preferred for this test because it is sufficiently reactive to fuse with the organic compound but not so reactive that it becomes hazardous or uncontrollable.Potassium is not used in the Lassaigne test because it is significantly more reactive than sodium,making the reaction dangerously vigorous and difficult to handle.Therefore,the Assertion is incorrect,and the Reason is correct.

Test	Inference
$a$. Dil. $HCl$	Insoluble
$b$. $NaOH$ solution	Soluble
$c$. $Br_2/\text{water}$	Decolourization

Assertion: Potassium can be used in the Lassaigne test.
Reason: Potassium reacts vigorously.
